1.9.5.4 Air Filter

The NE40E-X16 draws in air from the front and exhausts air from the rear. The two air filters
on the upper and lower chassis are identical. To maximize air intake, the filters are fully
perforated. Air filters are fixed to the chassis by fasteners to facilitate filter removal and
replacement. Figure 1-87 shows the appearance of an air filter.

The air channel in the SFU slot area is located on the left of the chassis. The air filter uses
front access. The depth of the air filter is the same as that of an SFU and the height of the air
filter is four times the height of an SFU as shown in Figure 1-88.
